TYPO3 Core

See screenshot.

If the record is expanded and i save the aggregate record, so on the next response the IRRE record is loaded statically, the category tree is rendered. If i collapse the IRRE Record and save the aggregate, so i have to do an ajax request to expand it again, the tree will not be rendered.

Happens - afaik - in the last view sprint releases, i first recognized it in 7.1 i think and it is still present.

The problem might be the renderMode=tree, but this is simply a shot in the dark.
